On the basis of the first-order fiber Raman amplifier, the second-order fiber Raman amplifier adds a pump laser in the 13xxnm band to provide Raman gain for the first-order Raman 14xxnm laser, which can effectively increase the performance of the Raman amplifier and is suitable for use in Optical signal amplification for longer distance unrepeatered optical transmission systems. The second-order fiber Raman amplifier needs to be used together with the first-order fiber Raman amplifier.
